IMPROVED MACHINE FOR SHAPING HEELS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 12,33% dated April 12, ISM.

To @ZZ 1077.071?, it may concern.'

Be it known that I, JAMES SAMUELS, a resident or" Lynn, in the county of Essex and State of Massachusetts, have invented an Improved Machine for Shaping Heels for Boots or Shoes; and I do hereby declare the same to be fully described in the following specication, and representedin the accompanying drawings, of which- Figure l is a top view, Fig. 2 a side eleva tion, and Fig. 3 a vertical and longitudinal section, ot' it.

In my said machine I make use of but one pattern for shaping a heel of any ordinary size, and employ with the said stationary or fixed pattern an adjustable cutter or knife, which is not only adjustable in directions toward and from the heel-clamp, butis provided with a means ot' lateral adjustment whereby the said cutter or knife may be still further adjusted with reference to the said heel-clamp or a piece of leather when xed in the machine. Furthermore, I have a peculiar arrangement ot' a treadle and an Yauxiliary heel-cutter with reference to the table and stand for supporting the heel-clamp. I also have a peculiar arrangement ofthe spring which keeps the knifecarrier up to the pattern. The auxiliary knifeguide is also arranged so as to cause the said knife to make a slanting cut through the leather.

In the dra-wings, A denotes the table or stand ofthe machine, it being provided with an arm or standard, B, which is so applied to a post, C, as to be capable of sliding vertically thereon. VlVithin the post C there is a spring, l), for forcing upward the standard B, which for being depressed is provided with a foottreadle, E, the latter being connected with the standard by a connecting-rod, F, the whole being arranged as shown in the drawings.

For holding the treadle E down when depressed a stationary rack, Gr, extending from the table, is employed, the treadle being so applied to the table as to be capable of being engaged with the rack and disengaged therefrom as circumstances may require.

From a seat or projection, H, elevated on the table A, a cylindrical journal or post, I, projects upward and extends into and supports in position a pattern-cam, K, and a block, L, on which the leather or pieces of and embracing the post I, so as to be capable of revolving thereon, is a lever, N, in which there is a helical spring', O, which is provided with a head, that bears at one end against the post I, as shown in Fig. 3. This spring serves to draw the part a, by which the cuttercarrier b is supported, close up to the periphery of the pattern-cam, the head of the spring,

while the lever is in the act of being revolved on the said post I, bein g caused to turn against the post and with the lever. The cutter-carrier b is dovetailed into the part a or into a dovetailed groove, c, which is arranged in such part a, and transversely ot' the lever N, the groove admitting ot" the carrier being adj usted or moved laterally relatively to the lever. The cutter I?, whose shank extends horizontally through the carrier b and is clamped therein by a screw, d, rests on the upper surface of the block or part a, in consequence of which the screw d can be used for two purposes-viz., that of fixing the cutter in its carrier and also that of clamping the latter to the block a. By revolving the lever N on the post I the cutter will be caused to traverse through the leather when clamped on the block L and the said cutter will be guided in the proper direction by means of the pattern-cam. Furthermore, there is applied to the standard B, and in advance of the clamp thereof, a chisel or auxiliary cutter, It, its shank being so applied to such standard as to be capable of moving up and down thereon. The cutter and its shank e are not arranged perpendicularl y to the top surface ofthe block L, but are disposed at an inclination thereto soV as to cause the cutter while being depressed to make a slanting cut through the leather. This cutter B is not only provided with an elevatingspring, S, arranged on one side of the standard B, but it has a means or mechanism for depression of such cutter, such being a lever, T, and a treadle, U, united by a connectingrod, V, the whole being arranged as shown in the drawings, the lever T having its fulcrum a ried or supported by a projection, f, erected upm the standard B.

'lhe part a hereinbefore mentioned has a journal, g, p1r ojecting vertically from it and into the lever N. This journal by revolving freely within the lever enables the part a to turn and adapt itself to the periphery of thc patterncam, the form of the part a being as represented in top view in Fig. 4. With my said machine I am enabled to effeet the shaping of the front of the heel (by the auxiliary cutter or chisel) by means of a foottreadle, instead ot' by a handlever, so applied to the standard B as to work transversely thereof andv be operated by the hand of an attendant, thus operating-more or less by the weight of the attendants body rather than by thc force of his arm alone, the treadle rendering it easier and less fatiguing for him to operate the machine in the matter of forcing the auxiliary cutter downward. By the peculiar means of adjustment of the main cutter it can be adjusted to better advantage as it may become worn or as circumstances may require than were it adjustable only in directions longitudinally of the lever by which itis operated.

I claim as my invention- 1. The improved machine as not only constructed with mechanism for supporting the leather and shaping it in the form necessary tor a heel, but having a treadle, U, and an auxiliary lever, T, arranged andoombined together and with the table A and the movable standard B, substantially in manner and so as to operate as described.

2. The improved machine as not only constructed with mechanism for supporting the leather and shaping it in the form necessary for a heel, but as having its heel pattern cam stationary and its cutter l? provided with adjustin g devices, all substantially as described,

whereby such cutter may be adjusted not only for heels of different sizes, but in other respects, as explained.

3. The arrangement of the cutter-carrier spring O within the lever N, and so as to bear by means of its head against and turn on the post I, substantially in manner and under cir cumstanoes as specified.

4. The improved machine as not only constructed with mechanism for supporting the leather and shaping it into the necessary form for a heel, but as having its auxiliary cutte or chisel R so arranged and applied to the standard B that while being depressed it will make a slantin g cut through the leather or a cut inclined to the upper surface of the blockV for
